- 1Stem size is the average stem size (m3) scanned during each hour. Group A and Group B operators were indicator variables for single operators whose productivity was different from members within other groups, but not with members in the same group. Note that the default operator value was when two or more people scanned stems within the same hour.
- 2SBandE was an indicator variable for those hours in which a scheduled break occurred or in which end-of-shift work was undertaken.
